' PAPER CONTAINER.

Application filed May 22,1923. Serial No. 640,697.

To all whom it may canoe-m; Y

Be it known that I, ERNEs'T R. I'IUNTLEY, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles 7 andState of California, have invented new and Useful Improvements in PaperCon- .tainers, of which the following is a specification. a

This invention has relation to containers formed of paper for holdingsemi-solid substances, and refers more specifically to a novel form ofcover locking seat formed on its rim. Heretofore inexpensive die formedpaper containers have been used for holding dry substances, such ascandy, dates, nuts, and similar articles that are unlikely to be spilttherefrom during transportation, but as far as I am able to determineno; inexpensive paper container has been-constructed hav' mg an annularcover'locking rim formed.

thereon for the reception of a flat paperdisk cover.' In my improvedconstruction, the annular rlm'of tlie-conta1ner 1s so folded and formedthat a simple ,paper'disk cover can be readily attached thereto andsecurely held thereon without the use of a sealing niaterial oralmechanical means, the resiliency of' the container walls holding thedisk cover against accidental displacement,thereby adapting the same forholding semifluid 'foodsor substances that are -l1kely to be spiltduring transportation of thecontainer.-

I An important object of this invention is toprovide a novel form of dieformed cover seating rim for paper containers that will securely hold .afiat cover in position thereon without danger ofaccidental-displacement.

The above and other incidental objects of asimilar nature, which will behereinafter more specifically. treated, are accomplished by -suc h meansas illustrated in the accompanying drawings, described in the followingspecifica ion, and then 'more particularly pointed ut in the claim whichis append 'ed hereto and forms a part of this application. I 1 1 is adiagrammatic detail view of the rim portion of a die formed papercontainer illustratin the rim cover ing seat.

1 Fig. 2 is a view similar to Fig. 1 showingi another form of coverlocking seat.

Fig. 3 is asimilar view illustrating a frictionalcover seat.

Figs. sand 5 are views'similarto the pre the method of forming,

ceding views showing further forms of cover locking seats.

Fig. dis a perspective view of a paper folded side walls 7 The annularedge of the I container of the form illustrated in Figs. 1, 6 and 8,after the same hasbeen formed, is folded outwardly and downwardly ashort distance as at 8, then upwardly as at 9, and finally downwardlyand inwardly as at 10, the edge 11 terminating just above the edge 12formed by the first folding operation, the

twoadjacent edges 11 and 12 forming an annular cover locking seat 13,all the folds being pressed together on the completion of the variouscover seat forming operations as clearly shown in the completedcontainer illustrated in Figs. 6 and in the sectional detail of 8 of thedrawings.

The form illustrated in Fig. 2,,is substan tially the same form as.illustrated in Fig. 1, except an outwardly extending annular flange 14is substituted for the fold 8, to

'forni'an annular seat for the disk cover 15, stamped or cut-from asheetof paper of the desired thickness. Frore fliebuter annular edge offlange 14 a wall 16 extends upwardly a short distance and is then bentdownwardly and'inwardly upon itself, its raw edge 18 terminating atshort distance above the flange 14 to form an annular cover locking seat13 of the same form as shown in Fig. 1. By omittingthe fold 8 in the 199above described form I- am enabled to slightly decrease the oostofconstruction, althoughthe formed edge or cover locking seat will nothave the stability of the form illustrated in Fig. 1, the fold 8 of saidform I also tending to prevent the accidental unfolding of the plaitedside 'wallsof the contalner.

In Fig. 3, the upper edge of the container wall is first folded or bentdownwardly and U" outwardly as at 20', and then the wall extendsupwardly as at 21, the extreme upper edge being bent downwardly andinwardly as at 22, the annular edge 23 terminating below the edge orseat 24 formed by bend 20 so that when the container is completely fin--sisting of three folds of paper, this rendering the annular edge of thecontainer of a.

more rigid form, and at the same time concealing the raw edge 26 of thepaper.

In order -to increasethe depth of the cover locking seat groove, theupper annular edge of the container 5"is bent as shown inFig. 5, theannular-flange 1d being the same as in the forms shown in Figs. 2 and4.- After completing the formation of flange 14,- the upper portion ofthe wall 7 is bent upwardly as at 27, then downwardly and inwardly as at'28, then upwardly as at 29, the end 30 being bent outwardly upon wall29, the extreme end 31 chambering between walls 28 and 29, the entireformation being pressed compactly together in the completed eontainer.By means of this construction the upper rim is greatly strengthened, anda locking seat -is'formed from which it will be impossible to remove thecover when mounted therein without destroying or ren-' dering uselessfor other purposes the container.

' upwardly and In Fig: 7 is shown a rectangular container formed on itsupper edge with a cover looking seat, preferably of the form shown inFig. 1, although the other illustrated forms could be used if desired.In this form, the cover 15 will be held in locked relation to thecontainer as in the cylindrical forms. The cover- 15 which is of diskform for the cylindrical containers, is formed of a single thickness ofpaper, its diameter being slightly greater than the diameter of thecontainer at the locking seat groove 13, so that when it is mounted inthe annular seat groove 13 the resiliency of the container walls willhold the same securely in position thereon.

From the above description it will be observed that I have produced asimple form of cover locking seat for inexpensive paper containers, thatwill securely hold the cover in place without the necessity of employingsealing material such as paraifiue wax, or separate cover fasteningmeans.

\Vhat I claim is: 4

As anarticle of manufacture,-a paper'container formed of a single blankhaving plaited side walls andhavingthe upper end of its walls bentoutwardly and downwardly to form an inner annular ledge then bentdownwardly upon itself and terminating above the said ledge to form withsaid ledge a cover locking groove, the width of the locking groove beingsubstantially the same as the thickness of the cover, and a flat covermounted in said groove, the resiliency of the side wall permitting theinsertion of the cover in the locking groove.

In witness-that I claim the foregoingl 1 have hereunto subscribed myname this 3rd day of May, 1923.

ERNEST R. HUNTLEY.
